Glossary of terms
Acute Description of a disease with rapid onset, severe symptoms and short duration.
Adenocarcinoma A malignant tumour of glandular tissue.
Adjuvant therapy A treatment given in addition to the main treatment, for example chemotherapy or radiotherapy after surgery to prevent the cancer from coming back and to improve cure rates. Adjuvant treatment aims to augment the effectiveness of the primary treatment.

Head and Neck Cancers of the face, jaw, mouth and voice box.
Hodgkin’s Disease A cancer of the lymphatic system.
Hormone therapy Diverse group of drugs which are beneficial in cancer therapy by blocking the substance which stimulates the cancer cells e.g. Tamoxifen for breast cancer.
Immunotherapy Treatment that stimulates the body’s immune system to fight cancer. Interferon and Interleukin 2 are immunotherapies.
Improving Outcomes Guidance (IOG) Site specific cancer guidance on the organisation and delivery of cancer services by tumour group, published by the National Institute for Health and Clinical Excellence (NICE)
Invasion Term used in oncology to describe the destruction of healthy tissue by a malignant tumour.
Ipsilateral One side of the body.
Laparoscopy Procedure using a flexible tube of optic fibres to look inside the abdomen and pelvis without having to make large incisions and collect tissue samples.
Leucopoenia Reduction in the white cells often caused by cytotoxic drugs.
Localised Cancer A cancer that only involves the tissue where it started and the tissue next to it.
Lumpectomy Removal of malignant lump (usually a breast lump) while conserving as much of the normal tissue around it. Now referred to as a partial mastectomy.
Lymph Glands/Nodes Glands/nodes fight infection and filter body fluid particularly in the armpits, neck and groin.
Lymphatic system Made up of lymph glands, lymphatic vessels and the spleen.
Lymphoma A cancer of the lymphatic system.
Lymphocytopenia Decrease in the number of lymphocytes in the blood.
Lymphoedema Swelling due to abnormal accumulation of lymph fluid when the vessels are blocked, damaged or removed.
Malignant Tumour that is invasive and destroys the tissue in which it originates. A tumour which will metastasise and will often cause harm.
Mammogram/Mammography X-ray examination of the breast to look for the early signs of cancer.
Marker Chemical substance produced by a cancer and can be used to monitor the progress of the disease, usually with a blood test.
Melanoma Skin cancer, often as a result of excessive exposure to sunlight.
Metastases/Mets Areas where cancer has spread to such as bones or liver.
Mortality rate Mortality statistics mean the number of people per population who have died from a particular type of cancer in a year. These figures should be looked at alongside incidence figures and other statistics.
MRI Magnetic Resonance Imaging, scan using magnetism to build up a picture of organs and tissue.
Mutation A change in a gene. If a gene is mutated the protein it makes will be abnormal and it can alter how a gene works.
Myeloma Cancer that develops from the plasma cells of bone marrow.
Myelosuppression Reduction in blood cell production by bone marrow which can occur after chemotherapy.
Neutropenia Decrease in the number of white cells (neutrophils) which can occur after chemotherapy.
NMR Nuclear Magnetic Resonance.
Non Small Cell Lung Cancer (NSCLC) Includes squamous cell, adenocarcinoma and large cell lung cancers. They are grouped together as they behave in a similar way and respond to similar treatments.
Oncologist Specialist doctor treating cancer. A clinical oncologist treats patients with radiotherapy, chemotherapy and hormone therapy. A medical oncologist specialises in chemotherapy and hormone therapy.
Palliative Treatment Medication, treatment or care that gives temporary relief of symptoms such as pain and sickness but does not cure the disease.
Peer review National Cancer Peer Review (NCPR) is a national quality assurance programme for NHS cancer services. The programme involves both self-assessment by cancer service teams and external reviews of teams conducted by professional peers, against nationally agreed “quality measures”.
PET scan Positron Emission Tomography. A whole body scan using a radioactive drug (tracer) which can show areas of suspicious high activity which need to be investigated further.
Primary Cancer/Tumour Site where the cancer starts. The type of cell that has become cancerous will be the primary cancer. If a liver biopsy has cancerous breast cells then the primary cancer is breast cancer.

PSA test Prostate Specific Antigen test. A blood test used to diagnose and monitor prostate cancer.
Quality Standards Set of specific, concise statements that act as markers of high-quality, cost-effective patient care, covering the treatment and prevention of different diseases and conditions, published by the National Institute for Health and Clinical Excellence (NICE).
Radiotherapy Cancer treatment using high energy X rays. It can take the form of external beam radiotherapy which is conformed to target the tumour site whilst minimising radiation to surrounding tissues. Gys (Grays) are the units that the radiation dose is measured in.

Secondary Cancer/Secondaries Cancer spread, cells have broken away from the primary tumour and spread to another part of the body where they have started to grow.
Spinal Cord Compression A condition which needs prompt treatment as the damage done to the spinal cord by a primary tumour or metastastic disease can cause paralysis.
Squamous Consisting of a single layer of plate like cells. A covering resembling scales.
Staging Most cancers have four stages. Each stage relates to the size of the tumour and if it has spread.
Survival rate What survival means is that x% of patients were alive x% years after they were diagnosed.
Systemic treatment Treatment affecting the whole body.
Tumour A growth or enlargement that causes a swelling. It is also called a neoplasm. A tumour can be localised or spreading, harmless or cancerous. It is named after its location or its cellular make up or after the person who identified it.
